Effect of sodium-potassium pump inhibition by ouabain on the permeability of isolated visceral sheep peritoneum
(2007)The permeability for small solutes and the ultrafiltration capacity of the peritoneum are essential for effective peritoneal dialysis (PD) treatment. Elucidation of the factors that regulate these two properties is therefore ... -
Effect of somatostatinergic analogues on the ischemia-induced release of [3H]-D-aspartate and [3H]-GABA from rat retina and hippocampus
(2008)The modulation of the enhanced release of [3H]-D-Aspartate and [3H]GABA following ischemia-like conditions was studied in rat retinal and hippocampal preparations using a superfusion system. Ischemia was simulated by a ... -
Effects of grape extracts on the in vitro activity of enzymes involved in oxidative stress regulation
(2011)Background/Aim: A number of in vitro and in vivo studies have investigated the potential preventive activity of grape extracts against different diseases, and have mostly focused on their antioxidant properties. The present ... -
Efforts to create an artificial testis: Culture systems of male germ cells under biochemical conditions resembling the seminiferous tubular biochemical environment
(2005)Induction of meiotic and post-meiotic alterations of male germ cells in vitro has been the target of several research efforts since 1960. However, to date, the establishment of an ideal culture system in which spermatogonial ... -
Enhancement of the transmesothelial resistance of the parietal sheep peritoneum by epinephrine in vitro: Ussing-type chamber experiments
(2005)The peritoneal mesothelium constitutes an ion transport barrier that is taken advantage of in peritoneal dialysis. The aim of this study was to investigate the effects of epinephrine on the electrical transmesothelial ... -
Enhancer of rudimentary homologue interacts with scaffold attachment factor B at the nuclear matrix to regulate SR protein phosphorylation
(2017)Scaffold attachment factor B1 (SAFB1) is an integral component of the nuclear matrix of vertebrate cells. It binds to DNA on scaffold/matrix attachment region elements, as well as to RNA and a multitude of different proteins, ... -
ERK signaling controls productive HIF-1 binding to chromatin and cancer cell adaptation to hypoxia through HIF-1α interaction with NPM1
(2021)The hypoxia-inducible factor HIF-1 is essential for oxygen homeostasis. Despite its well-understood oxygen-dependent expression, regulation of its transcriptional activity remains unclear. We show that phosphorylation by ... -
ERK1/2 phosphorylates HIF-2α and regulates its activity by controlling its CRM1-dependent nuclear shuttling
(2019)Hypoxia-inducible factor 2 (HIF-2) is a principal component of the cellular response to oxygen deprivation (hypoxia). Its inducible subunit, HIF-2α (also known as EPAS1), is controlled by oxygen-dependent as well as ... -
Extracts from the mediterranean food plants Carthamus lanatus, Cichorium intybus, and Cichorium spinosum enhanced GSH levels and increased Nrf2 expression in human endothelial cells
(2018)The Mediterranean diet is considered to prevent several diseases. In the present study, the antioxidant properties of six extracts from Mediterranean plant foods were assessed. The extracts' chemical composition analysis ... -
FGF-2 and HGF reverse abiraterone’s effect οn intracellular levels of DHT in androgen-dependent and androgen independent prostate cancer cell lines
(2020)Purpose: Growth factors such as fibroblast growth factor 2 (FGF-2) and hepatocyte growth factor (HGF) appear at high levels in prostate cancer (PC). Abiraterone is an androgen biosynthesis inhibitor which is currently in ... -
Genome-Based Metabolic Reconstruction Unravels the Key Role of B12 in Methionine Auxotrophy of an Ortho-Phenylphenol-Degrading Sphingomonas haloaromaticamans
(2020)Auxotrophy to amino acids and vitamins is a common feature in the bacterial world shaping microbial communities through cross-feeding relations. The amino acid auxotrophy of pollutant-degrading bacteria could hamper their ... -
Glucose Derivative Induced Vasculopathy in Children on Chronic Peritoneal Dialysis
(2021)RATIONALE: Patients with chronic kidney disease (CKD) have an exceedingly high cardiovascular risk; which further increases in patients on peritoneal dialysis (PD). The pathophysiological role of reactive metabolites ... -
Heat shock protein 70 improves in vitro embryo yield and quality from heat stressed bovine oocytes
(2021)Heat shock protein 70 (HSP70) is a chaperon that stabilizes unfolded or partially folded proteins, preventing inappropriate inter-and intramolecular interactions. Here, we examined the developmental competence of in vitro ... -
HIF-2α phosphorylation by CK1δ promotes erythropoietin secretion in liver cancer cells under hypoxia
(2016)Hypoxia inducible factor 2 (HIF-2) is a transcriptional activator implicated in the cellular response to hypoxia. Regulation of its inducible subunit, HIF-2α (also known as EPAS1), involves posttranslational modifications. ... -
Human coronaviruses in idiopathic Parkinson's disease: Implications of SARS-CoV-2's modulation of the host's transcriptome
(2021)Objective: A recent study on the effects of SARS-CoV-2 infection on the host's transcriptome indicated the perturbation of several pathways associated with neurodegeneration, including but not limited to Parkinson's and ... -
Human mesenchymal stem cells with enhanced telomerase activity acquire resistance against oxidative stress-induced genomic damage
(2017)Background Human mesenchymal stem cells (MSC) are important tools for several cell-based therapies. However, their use in such therapies requires in vitro expansion during which MSCs quickly reach replicative senescence. ... -
Humoral response in experimental autoimmune encephalomyelitis targets neural precursor cells in the central nervous system of naive rodents
